It is a deliberate attempt to avoid looking at the flaws of the sports culture which exploits and damages these young men. It also as repercussions for society in general but that's not a gun issue.
It's a PR coverup for the NFL.
I totally agree with this post. The NFL is a big business, and like any business it is ALL about money. This is a way to deflect the discussion away from brain injuries, and potential huge losses in liability suits to gun control. The sports culture and sports media is largely very liberal.
